Rb26 Race Head

[DoughBoy]

Selling my RB26, was built as a full-on item for a 1200hp motor. All work was done by RAMS head service in Windsor, they were responsible for GTR-700's head initially and learnt alot about RB heads from JUN - and were getting better results than them as well.

Parts list:

Custom 1mm oversize stainless valves (when I got the head done in 2004 off the shelf items were not available, made from Ferrea alloy blanks)

Aftermarket valve guides

Apexi V-Max SPL springs, retainers and buckets

Apexi V-Max SPL 280 degree 11.5mm lift cams (also have Tomei 290/11.5 and HKS 300(?)/11.5 cams as well)

Tomei camshaft stud kit

Trust cam gears

New stem seals

Also have ported injector base/manifold to suit head

Labor list

Ported intake + exhaust runners

Profile guides

Polished + cc'd chambers

Unshroud valves in chamber

Flow benched and runner flow equalised

Steam hole modifications/water gallery modifications

Clearanced for high lift cams

Drilled for 1/2inch head studs

Flow figures:

Have spent over $10,000 on this item (RAMS alone was $5500 with no parts) , had some big plans for my R33 but have gone a different route now. I also have a Harris Engine ported head here too (same people SydneyKid uses and raves on about) and it is nothing compared to this RAMS head.

Benefits of having such a modded head are quicker turbo spooling (or capacity to spool a larger turbo reasonably), more power(!!!) and to a degree lower intake temps (due to less boost needed to make xyz power figure etc).

$8,000 or near offer, located in Sydney. Item is still unused, have mocked engine up a few times for clearancing/ ricer pictures but that's about it.

Couple of pics of the head, 3rd pic is of the ported intake against a standard head to show how much material was removed on the ports.
